ABSTRACT:
A guide for guiding a pump-rod in a well-head consisting of a housing capable of being held between a well-head tee and a stuffing box comprising an enclosure having two pairs of transversely rotatable rollers positioned substantially at right angles to each other, each roller of each pair being offset from the center line of the pump-rod such that the pump-rod will pass between both sets of rollers so that it will be guided during operation in a reciprocating path.
